AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE RALEIGH NC 129 PM EDT WED JUL 14 2004 .SHORT TERM (TONIGHT THROUGH FRIDAY NIGHT)... HEIGHT FALLS CONTINUE THIS AFTERNOON IN ADVANCE OF A LARGE TROUGH ALOFT IN THE OHIO VALLEY...THEN STABILIZE TONIGHT. THE 850 THERMAL GRADIENT NEAR THE MOUNTAINS AT 18Z SHOULD PROGRESS THROUGH THE PIEDMONT BY 00Z AND EAST BY 06Z TONIGHT SIGNALING COOL AIR ADVECTION INTO THE AREA EARLY TONIGHT. WITH CORRESPONDING DRYING OF THE COLUMN...CONDITIONS SHOULD STABILIZE AND DISSIPATE THE THREAT OF DEEP CONVECTION SHORTLY AFTER NIGHTFALL. THURSDAY-FRIDAY NIGHT...AN UNUSUALLY DEEP TROUGH ALOFT FOR MID JULY REMAINS OVER THE EASTERN U.S. THOUGH MIXING SHOULD BE ENHANCED UNDER A TROUGH...A STRONG SUBSIDENCE ZONE AT MID LEVELS AND DRY AIR SHOULD INHIBIT DEEP CONVECTION ON THURSDAY. SUBSIDENCE WEAKENS AS A SHORT WAVE AND WIND MAX ALOFT TRANSITS THE AREA EARLY FRIDAY. THIS ALLOWS MID LEVEL LAPSE RATES TO REACH OR EXCEED 6.5 DEG C/KM. A SLIGHT MOISTENING OF THE COLUMN MAY ALLOW A FEW TOWERING CU OR EVEN AN ISOLATED SPRINKLE ON FRIDAY...BUT POPS WILL REMAIN BELOW 15 PCT. NO MAJOR CHANGES FROM PREVIOUS FORECAST TEMPERATURE/DEWPOINT GRIDS ARE EXPECTED. && .LONG TERM (SATURDAY THROUGH WEDNESDAY)... PERSISTENT EASTERN TROF AND SURFACE LOW PRESSURE THROUGH THE PERIOD MAKE IT DIFFICULT TO RULE OUT LATE DAY CONVECTION EACH DAY SUNDAY THROUGH WEDNESDAY. IT WOULD APPEAR THAT CHANCES WILL BE BEST SUNDAY AND SUNDAY NIGHT AS THE INITIAL FRONT PUSHES THROUGH. LOW LEVEL MOISTURE APPEARS TO BE LIMITED BUT WILL INTRODUCE SLIGHT CHANCE POPS DAYS 4-7 DUE TO THE UNCERTAINTY OF FRONTAL POSITION EARLY NEXT WEEK. LITTLE CHANGE IN TEMPS WITH HIGHS RANGING FROM 85 TO 90 THROUGH THE PERIOD. && .AVIATION... SCATTERED TSRA THROUGH LATE AFTERNOON...PERHAPS EARLY EVENING IN THE EAST ARE EXPECTED AS THE VORT AXIS MOVES ACROSS THE AREA. SKIES CLEARING EARLY TONIGHT AS DRYING WORKS ITS WAY TO THE SURFACE.
